Dehydroacetic acid is a synthetic preservative used in cosmetics and personal care products. It is effective against a wide range of bacteria and fungi, making it a popular choice for use in products such as shampoos, conditioners, and moisturizers. It is considered to be a low hazard for human health and for the environment. Clinical tests have shown present inclusion rates of dehydroacetic acid (less than 0.6%) to be non-irritating and safe for use in cosmetics. It is often combined with benzyl alcohol to enhance its effectiveness.
